Hello everyone, I am in need of urgent opinions!
Tomorrow morning a contractor will be installing a gas line for my new Hayward H250FDN heater. This is a new heater, my pool never had heating before.
The problem: the distance for the new gas line will be about 70-75 feet, and the gas supply is what is "natural gas low pressure". According to the heater manual, a pipe with diameter 1 1/4 should be used for 50-100 feet. However, my installer insists that the 1 inch pipe is fine.
Please, tell me what you think about that, because I'm about to freak out
